VC60B+ Electronic Megohmmeter 250/500/1000V LCD Backlight Insulation Resistance Tester
Feature:
1. Adopt low loss high transform ratio inductance energy storage type DC voltage converter, which can convert 9V voltage into 250V/500V/1000V DC voltage.
2. Using a digital bridge, it has a wide range and can lock test data to facilitate measurement in more situations.
3. Beautiful and high?grade appearance, stable performance, light and easy to use, can work with both hands after using the strap.
4. It is suitable for insulation resistance testing needs of motors, cables, electromechanical equipment, telecommunications equipment, power facilities, etc.
5. LCD digital display screen, it has a backlight display function, clear data, more convenient to measure and record data.

Note:
1. When the test switch is pressed, the "E" output terminal will output a high voltage. Use it with care to avoid electric shock.
2. During the test, first check whether the test voltage selection and the test voltage prompt on the LCD are consistent with the required voltage.
3. During the M¥Ø test, if the displayed reading is unstable, it may be caused by environmental interference or unstable insulation material. At this time, you can connect the "G" terminal to the shielding end of the object to be tested to stabilize the reading.
How to use: 1. Turn the knob to the corresponding function according to the measurement needs.
2. Connect the electrode of the measured object to the corresponding socket of this instrument.
3. When testing the cable, connect jack G to the protective .
4. Press the test switch, the test will proceed immediately, and the reading will be available when the displayed value is stable. Press to rotate to the right to lock for continuous testing, and rotate to the left to release continuous testing. When the test switch is pressed, the high?voltage red warning light is on, the high?voltage display appears on the screen, and the buzzer emits a "di?di" sound. When the measured insulation resistance is less than 5% of the measuring range or is short?circuited, the buzzer will emit a long sound to warn.
5. Connect the red test lead "E" to the end of the line to be tested, and connect the black test lead "L" to the ground of the tested object; the "E" lead is required to be left as open as possible.
6. If only the highest digit displays "1", it means the range is over, and you need to select a higher range.
